This study proposes a method combining dynamic simulation and experimental impact-force data to quantitatively determine the dynamic characteristics of a Masset hammer throughout the entire operating process, particularly the impact acceleration, which is difficult to determine experimentally. An impulse absorption coefficient, η, is introduced to regulate the relationship between the force measured at the anvil and the actual force acting on the hammer, thereby ensuring that the calculated results are consistent with actual physical conditions. The results show that only a portion of the impact energy is transmitted to the anvil, while the remaining part is dissipated due to the energy-absorption characteristics of the structure; this provides a direct quantitative basis for selecting the test conditions. The proposed method does not require material modeling in the contact region and can be applied to similar hammer systems.
